MIDDLEWEIGHT DIVISION (UP TO 185 POUNDS)
1. Robert Whittaker (19-4)
In a span of three months, Whittaker knocked out Ronaldo "Jacare" Souza and edged Yoel Romero in a five-round battle. That's about as impressive as it gets. Next up: A UFC title fight against Michael Bisping.
2. Luke Rockhold (16-3)
After missing an entire year to knee injury and lack of opponent options, Rockhold returned to the win column with a finish over David Branch in September. The middleweight division has been something of a mess since Rockhold forfeited the UFC title Michael Bisping in 2016. He's eager to restore order.
3. Yoel Romero (12-2)
Romero came close to capturing the UFC's interim title, but couldn't outlast Robert Whittaker at UFC 213. He certainly has (plenty) bounce back potential, but time is also of an essence. He's on the plus side of 40.
4. Michael Bisping (30-8)
The UFC champion recorded his first defense in October, but it was a more difficult fight than many expected going in. Dan Henderson gave Bisping all he could handle in a five-round fight. Contenders are licking their chops at the thought of taking Bisping's belt. He has a rather large target on his back.
Next: UFC Fight Night on Nov. 24, vs. Kelvin Gastelum
5. Gegard Mousasi (43-6-2)
Mousasi barely snuck by Alexander Shlemenko in his Bellator debut in October. It probably wasn't the glorious showcase Bellator had in mind when it snatched Mousasi from the UFC, but a win is a win and Mousasi is still very much a title contender
6. Derek Brunson (18-5)
Brunson is ready for his turn under the spotlight, following a big-time win over Lyoto Machida in Brazil. He's came up short in some big fights, but his knack for first-round knockouts has become rather astonishing.
7. Chris Weidman (14-3)
It will take a few more wins for Weidman to stand atop the middleweight division again, but at least for one night, it kind of felt that way again. Weidman was superb in a submission win over Kelvin Gastelum in July, in his native Long Island. Next: TBD
8. Jacare Souza (24-5)
Souza probably should have been granted a UFC title shot a long time ago, but that's not about to change following his shocking knockout loss to Whittaker. It goes without saying: Souza has plenty of bounce-back potential, but this loss is a big one.
9. Georges St-Pierre (26-2)
Ranking St-Pierre this low might confuse some, as he just won the UFC's middleweight championship. That's very true, but that's his only win in the last four years, and his only win at this weight class period. That's just not enough to rank him above some of the other elite names here, but if he stays at 185 and keeps winning, that'll change quick.
10. David Branch (21-4)
One loss to Luke Rockhold in September doesn't erase a five-year unbeaten run for Branch -- but this was a big shot for him to catapult himself up the rankings. He'll look to start a new streak in his next fight.
